Three-dimensional shoe tree model structure designing method based on different foot types

Abstract

The invention discloses a three-dimensional shoe tree model structure designing method based on different foot types. The three-dimensional shoe tree model structure designing method is characterized by including the following steps: 1, preparing materials to be graded; 2, carrying out size grading on a standard three-dimensional shoe tree model according to standard size parameters; 3, carrying out girth grading on the shoe tree model according to standard girth parameters; 4, carrying out foot arch grading on the shoe tree model according to standard shoe tree bottom center concavity values; 5, saving the materials. According to the three-dimensional shoe tree model structure designing method, a half size and a quarter size are added into original standard sizes after size grading is carried out, and the number of the shoe sizes in a shoe size system is increased to be thirty seven; meanwhile, due to the girth grading design and the foot arch grading design, the structures of the three-dimensional shoe tree model include five girth type structures and five foot arch type structures, the choices of the sizes of shoes manufactured through shoe trees manufactured through the structures of the three-dimensional shoe tree model are multiple, the number of shoe types in each size is twenty five, and the problem that the shoes are not fit with feet can be solved to the maximum degree.

Description

Technical field [0001] The invention relates to a shoe last design method, in particular to a three-dimensional shoe last model structure design method based on different foot shapes. Background technique [0002] Shoe last is a model for making shoes. The structure and shape of the last determines the shape and wearing comfort of the shoes. With the development of social economy, people pay more attention to the comfort of shoes, and enterprises have higher requirements for independent design and automated production. The necessity of digital shoe last design has been recognized by the industry, but the current shoe last design is not Without fully considering the regularity of the foot shape of the crowd, especially in the face of different fat, thin, and different arches, the existing shoe lasts are only designed to fit most people's feet, such as only one fat and thin type, one arch type, Can not satisfy users with different foot types to make it comfortable to wear.

Problems solved by technology

With the development of society and economy, people pay more attention to the comfort of shoes. Enterprises have higher requirements for independent design and automatic production of holes. The necessity of digital shoe last design has been recognized by the industry, but the current shoe last design is not The law of the foot shape of the crowd is not fully considered, especially in the face of foot shapes of different fat and thin and different arches. The existing shoe lasts are only designed to suit the foot shapes of most people. For example, there is only one fat and thin type and one arch type. Unable to satisfy users with different foot types to make them comfortable to wear
